The redundancy mode of the port. The possible values read, which report the redundancy mode of the port, are: standalone(1)...the port is not in any redundant pair. hwActive(2).....the port is the active companion in a hardware-redundant pair. hwStandby(3)....the port is the standby companion in a hardware-redundant pair. swActive(4).....the port is the active companion in a software-redundant pair. swStandby(5)....the port is the standby companion in a software-redundant pair. The values that can be written, which change the redundancy mode, are: standalone(1)...causes the software-redundant pair to be broken up. hwActive(2).....if the previous value was hwStandby(3), this value will cause the port to become the active port in the hardware-redundant pair (i.e., a switchover). hwStandby(3)....if the previous value was hwActive(2), this value will cause the port to become the standby port in the hardware-redundant pair (i.e., a switchover). swActive(4).....if the previous value was swStandby(5), this value will cause the port to become the active port in the software-redundant pair (i.e., a switchover). swStandby(5)....if the previous value was swActive(4), this value will cause the port to become the standby port in the software-redundant pair (i.e., a switchover). Notes: 1.) The value standalone(1) cannot be written to effect hardware-redundant pairs.
